CVE-2022-31153: OpenZeppelin Contracts for Cairo is a library for contract development written in Cairo for StarkNet, a decentralized ZK Rollup. Version 0.2.0 is vulnerable to an error that renders account contracts unusable on live networks. This issue affects all accounts (vanilla and ethereum flavors) in the v0.2.0 release of OpenZeppelin Contracts for Cairo, which are not whitelisted on StarkNet mainnet. Only goerli deployments of v0.2.0 accounts are affected. This faulty behavior is not observed in StarkNet's testing framework. This bug has been patched in v0.2.1.
The exploitability of CVE-2022-31153 depends on two key factors: attack complexity (the level of effort required to execute an exploit) and privileges required (the access level an attacker needs).
CVE-2022-31153 presents an accessible attack vector with minimal effort required. Restricting access controls and implementing security updates are critical to reducing exploitation risks.
A lower complexity and fewer privilege requirements make exploitation easier. Security teams should evaluate these aspects to determine the urgency of mitigation strategies, such as patch management and access control policies.
Attack Complexity (AC) measures the difficulty in executing an exploit. A high AC means that specific conditions must be met, making an attack more challenging, while a low AC means the vulnerability can be exploited with minimal effort.
Privileges Required (PR) determine the level of system access necessary for an attack. Vulnerabilities requiring no privileges are more accessible to attackers, whereas high privilege requirements limit exploitation to authorized users with elevated access.
Above is the CVSS Sub-score Breakdown for CVE-2022-31153, illustrating how Base, Impact, and Exploitability factors combine to form the overall severity rating. A higher sub-score typically indicates a more severe or easier-to-exploit vulnerability.
Below is the Impact Analysis for CVE-2022-31153, showing how Confidentiality, Integrity, and Availability might be affected if the vulnerability is exploited. Higher values usually signal greater potential damage.
The EPSS score estimates the probability that this vulnerability will be exploited in the near future.
EPSS Score: 1.077% (probability of exploit)
EPSS Percentile: 84.51%
(lower percentile = lower relative risk)
This vulnerability is less risky than approximately 15.489999999999995% of others.
